The full Cambridge International AS & A Level Biology course, AS and A Level: cells and the molecules of life, membranes, cell division, DNA and protein synthesis, transport, gas exchange, disease and immunity, then respiration, photosynthesis, homeostasis, coordination, inheritance, evolution, biodiversity and genetic technology.
Lesson 1 is free to try. The other 132 lessons in Biology and its exam practice are for schools on RudimentaryLabs.
Microscopes, the organelles of eukaryotic cells, prokaryotes and viruses.
Carbohydrates, lipids, proteins and water: how their structures match their jobs.
How enzymes speed up reactions, and what changes how fast they work.
The fluid mosaic membrane, cell signalling and how substances cross membranes.
How chromosomes are built and copied, and how cells divide by mitosis.
DNA and RNA structure, DNA replication, and how genes are used to make polypeptides.
Xylem and phloem: how water, minerals and sugars move through plants.
Blood vessels, blood, tissue fluid, gas transport and the heart.
The structure of the human lungs and how gases cross the alveolar wall.
Cholera, malaria, TB and HIV, and how antibiotics work and fail.
Phagocytes, lymphocytes, antibodies and vaccines.
ATP, respiratory substrates and the stages of aerobic and anaerobic respiration.
Chloroplasts, pigments, the light-dependent stage, the Calvin cycle and limiting factors.
Negative feedback, the kidney, blood glucose control and stomata.
Nerves, synapses, muscle contraction, and fast and slow responses in plants.
Meiosis, genetic crosses, statistics and how genes are switched on and off.
Variation, natural and artificial selection, allele frequencies and how new species arise.
How life is classified, how biodiversity is measured, and how species are protected.
Genetic engineering tools, PCR and electrophoresis, and uses in medicine and farming.
